Water saving toilet device

ABSTRACT

A water saving toilet device comprises a drain pipe of a basin connected with a flush unit of a toilet, thereby providing the wastewater, which is produced after the basin is used, into the flush unit of the toilet via the drain pipe to be a water for cleaning the toilet after the user used the toilet, achieving the effect of water saving.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates a water saving toilet device. Moreparticularly, a toilet device has the effect of water saving viareceiving the wastewater from a basin to be the cleaning water forwashing the toilet after the user used the toilet.

2. Description of Related Art

The traditional toilet device, such as a toilet bowl and a urinal,comprises a flush unit. After the user used toilet device, the flushunit is used to wash out the excreta.

For a toilet bowl, the flush unit comprises a tank, a supply pipe set inthe tank, a float ball set in the tank and connected with the supplypipe to control the water inflow via the supply pipe, and a flappervalve set in the tank and controlled by a handle set outside the tankvia a flush lever to open and close. When the handle is pushed to openthe flapper valve, the water in the tank is poured out from a flush pipewhich is connected to the tank to wash the toilet bowl and the waterlevel of the tank drops and the float ball drops, then, when the waterlevel is reached a default low level, the flapper valve is closed andthe water is poured into from the supply pipe to raise the water leveland float ball, finally, the water lever is reached a default highlevel, the influx of the water from the supply pipe is stopped to waitthe next flush.

For a urinal, a switch of the flush unit is directly connected with asupply pipe. When the switch is opened, the water is poured into thetoilet device via the supply pipe to wash the toilet device. When theswitch is closed, the supply pipe is closed to stop to supply water.

Furthermore, as we all know that washing hand after use toilet is acommon health habit. The wastewater which is produced after user washeshis hands is directly drained out without reuse again. However, thewastewater produced by washing hands belongs to clean wastewater to acertain degree. Therefore, if the wastewater produced by washing handsis became as the water for wash out the excreta in the toilet device,the consumption of water is saved.

SUMMARY OF THE INVENTION

Therefore, the object of the present invention is to provide a watersaving toilet device, in which the wastewater is received from a basinto be the cleaning water for washing the toilet after the user used thetoilet, resulting in the reuse of the water, achieving the effect ofwater saving.

For the above object, a water saving toilet device comprises a drainpipe of a basin connected with a flush unit of a toilet. The basin isset above the toilet or at the side of the toilet. The basin alsocomprises a tap for supplying water. Therefore, the wastewater producedafter the basin is used is provided into the flush unit of the toiletvia the drain pipe to be a washing water for cleaning the toilet afterthe user used the toilet, achieving the effect of water saving.

According to an embodiment, the water saving toilet device furthercomprises a storage rack, set above the basin or at the side of thebasin.

According to an embodiment, the toilet is a toilet bowl and the flushunit comprises a tank, a supply pipe set in the tank, a float ball setin the tank and connected with the supply pipe to control the waterinflow via the supply pipe, and a flapper valve set in the tank andcontrolled by a handle set outside the tank via a flush lever to openand close. When the handle is pushed to open the flapper valve, thewater in the tank is poured out from a flush pipe which is connected tothe tank to wash the toilet bowl and the water level of the tank dropsand the float ball drops, then, when the water level is reached adefault low level, the flapper valve is closed and the water is pouredinto from the supply pipe to raise the water level and float ball,finally, the water lever is reached a default high level, the influx ofthe water from the supply pipe is stopped to wait the next flush.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

A water saving toilet device of the present invention comprises a drainpipe 11 of a basin 1 connected with a flush unit 21 of a toilet 2. Thebasin 1 is set above the toilet 2 or at the side of the toilet 2, andthe basin 1 comprises at least one tap 12 for supplying water.

Please refer to FIG. 1 and FIG. 2, which are a three-dimensional viewand a side view of a water saving toilet device according to anembodiment of the present invention, respectively. The toilet 2 is atoilet bowl 2 a, and the toilet bowl 2 a comprises a flush unit 21 a.The flush unit 21 a comprises a tank, a supply pipe set in the tank, afloat ball set in the tank, and a flapper valve set in the tank. Thestructure of the flush unit 21 a is the same as the traditional flushunit of the prior art described above, it is not described here again.

After the user uses the toilet, the handle is pushed to open the flappervalve, the water in the tank is poured out from a flush pipe to wash thetoilet bowl 2 a and the water level of the tank drops and the float balldrops, then, when the water level is reached a default low level, theflapper valve is closed and the water is poured into from the supplypipe to raise the water level and the float ball, finally, the waterlever is reached a default high level, the influx of the water from thesupply pipe is stopped to wait the next flush.

FIG. 3 is a three-dimensional view of a water saving toilet deviceaccording to another embodiment of the present invention. The toilet 2is a urinal 2 b and the flush unit 21 b comprises a supply pipeconnected with the drain pipe 11 of the basin 1. The structure of theflush unit 21 b of the urinal 2 b is the same as the traditional flushunit of the prior art described above, it is not described here again.After the user uses the toilet and opens the tap 12 of the basin 1 forwashing the hands, the wastewater directly drains out of the flush unit21 b which is connected with the drain pipe 11 of the basin 1 forwashing the urinal.
